Types ¶
type NameValueType ¶
type NameValueType struct {
Name string `json:"name"`
Value interface{} `json:"value"`
Typ string `json:"type"`
}
NameValueType is a very simple struct with Name, Value and Type. It's meant for simple json structures used to communicate signing-info about typed data with the UI
func (*NameValueType) Pprint ¶
func (nvt *NameValueType) Pprint(depth int) string
Pprint returns a pretty-printed version of nvt
type TypedData ¶
type TypedData struct {
Types Types `json:"types"`
PrimaryType string `json:"primaryType"`
Domain TypedDataDomain `json:"domain"`
Message TypedDataMessage `json:"message"`
}
func (*TypedData) Dependencies ¶
Dependencies returns an array of custom types ordered by their hierarchical reference tree
func (*TypedData) EncodeData ¶
func (typedData *TypedData) EncodeData(primaryType string, data map[string]interface{}, depth int) (hexutil.Bytes, error)
EncodeData generates the following encoding: `enc(value₁) ‖ enc(value₂) ‖ … ‖ enc(valueₙ)`
each encoded member is 32-byte long
func (*TypedData) EncodePrimitiveValue ¶
func (typedData *TypedData) EncodePrimitiveValue(encType string, encValue interface{}, depth int) ([]byte, error)
EncodePrimitiveValue deals with the primitive values found while searching through the typed data
func (*TypedData) EncodeType ¶
EncodeType generates the following encoding: `name ‖ "(" ‖ member₁ ‖ "," ‖ member₂ ‖ "," ‖ … ‖ memberₙ ")"`
each member is written as `type ‖ " " ‖ name` encodings cascade down and are sorted by name
func (*TypedData) Format ¶
func (typedData *TypedData) Format() ([]*NameValueType, error)
Format returns a representation of typedData, which can be easily displayed by a user-interface without in-depth knowledge about 712 rules
func (*TypedData) HashStruct ¶
func (typedData *TypedData) HashStruct(primaryType string, data TypedDataMessage) (hexutil.Bytes, error)
HashStruct generates a keccak256 hash of the encoding of the provided data
type TypedDataDomain ¶
type TypedDataDomain struct {
Name string `json:"name"`
Version string `json:"version"`
ChainId *math.HexOrDecimal256 `json:"chainId"`
VerifyingContract string `json:"verifyingContract"`
Salt string `json:"salt"`
}
func (*TypedDataDomain) Map ¶
func (domain *TypedDataDomain) Map() map[string]interface{}
Map is a helper function to generate a map version of the domain
type TypedDataMessage ¶
type TypedDataMessage = map[string]interface{}
